Thanks a lot for all your effort to clean this up!

Is it possible to place this into qcom,tlmm-common.yaml? If the pattern
is only used to make "function" required for GPIOs, then it should not
matter if it matches just the prefix ("^gpio") or the exact set of
allowed GPIO numbers. The definition of the "pins" property will already
take care of validating those.
Or are there some Qcom SoCs where a GPIO without "function" is valid?
Thanks,
Stephan
